1、 Performance and characteristics

This product is a new polyol dispersant developed by our company on the basis of the original anionic polyacrylate dispersant, combined with the types and properties of imported dispersants. It is widely used in the dry ultra-fine grinding of ceramic clay, heavy calcium, talcum powder, titanium dioxide and other inorganic pigments. It is suitable for vertical mill, horizontal ball mill, ring roller mill and other dry ultra-fine grinding equipment, especially for powder grinding It can not only shorten grinding time, improve production efficiency, but also obtain uniform particle size distribution, so as to achieve the ideal dispersion effect.

This product is non-toxic, no corrosion, no special smell.

2、 Technical index

3、 Test method

1. Appearance: visual inspection.

2. Determination of pH value: according to GB / t6368-1993.

3. Specific gravity measurement: measurement with a hydrometer.

4、 How to use it

In the process of ultra-fine grinding, this product can be added directly with a metering pump without dilution. The amount of this product is 0.1-0.2% of the absolute dry pigment, and the output can be increased by 20-35%. If the grinding process has special requirements, it can also be added after dilution according to a certain proportion.

5、 Packaging

The conventional packaging of this product is 250kg / barrel (plastic barrel), and other packaging can be adopted according to the needs of users.

6、 Economic effect analysis:

In 2013, the customer test of a certain type of inorganic pigment grinding aid dispersant in a dry superfine grinding of calcium carbonate was analyzed

1、 Details of test manufacturer:

1. Grinding machine type: horizontal ball mill;

2. Grinder size: 3900 mm in diameter and 6900 mm in length;

3. Grinding machine output: 1250 mesh, calcium carbonate output 10 tons / hour;

4. Grinding machine power consumption: 96 degrees / ton, electricity 0.89 yuan / degree.

2、 Specific test process:

The production of inorganic pigment was measured at 8:00 a.m. and 8:00 a.m. in 2013

By 8:00 a.m. on May 9, 2013, the test was completed, and the total output of calcium carbonate was 238.8 tons after continuous operation for 24 hours.

On May 10, 2013, the formal test was started at 8:00 a.m., and the time and output (inorganic pigment grinding aid dispersant) were counted

The dosage is 12kg / h and added to the calcium carbonate feed inlet of horizontal ball mill by metering pump until May 11, 2013

At 8:00 a.m., the test was finished, and the total output of calcium carbonate was 297.6 tons.

3、 Economic benefit analysis:

1. Added value of calcium carbonate production: 297.6 tons - 238.8 tons = 58.8 tons

2. Consumption cost of inorganic pigment grinding aid dispersant: 12kg / h × 24h × 12.5 yuan / kg = 3600.00 yuan

3. Power saving: 58.8 tons × 96 kwh / ton = 5644.8 kWh

4. Electricity saving: 5644.8 kwh × 0.89 yuan / kWh = 5023.9 yuan

5. Total cost saving: 5023.90 yuan-3600.00 yuan = 1423.90 yuan

6. Cost saving per ton of calcium carbonate: 1423.90 yuan / 297.6 tons = 4.78 yuan / ton.

4、 The addition of inorganic pigment grinding aid dispersant not only increases the output of calcium carbonate, but also saves the man hour cost and reduces the production cost (the man hour cost saved is not included in this test).

5、 Adding inorganic pigment grinding aid dispersant, calcium carbonate powder is bulky and has good fluidity. Its compatibility with resin and dispersibility are obviously improved. It can effectively improve the market competitiveness of calcium carbonate products
